Eintracht Frankfurt coach Adi Hutter concedes they'll struggle to keep hold of Evan N'Dicka this summer.

The 21 year-old is being watched by several Premier League clubs, including Tottenham, Arsenal and Southampton.

Hutter admits he's delighted with the form shown by N'Dicka this season.

"Evan N'Dicka has made a great development," the Austrian said yesterday, “he always performs and impresses more and more with his skills on the pitch. He's never injured, he's at a top level physically and works incredibly hard."

Hütter also touched on N'Dicka's newly discovered goal threat.

"If he's scoring goals now, it will usually be difficult to keep him," he added.
